CAN'oIY Eon CEILING FIXTURES. 1

Application filed September 29, 1927. -Serial No. 222,769.

This invention relates to canopies for ceiling fixtures and the like and is an improvenient of my application Serial No. 187,017, filed April 27, 1927. Y

An object of the invention is to provide a more eliicient means forv lowering the canopy, f

which is used particularly on ceiling fixtures while connecting the wiring sections or while inspecting or making repairs thereon.

Another obj-ect is to simplify the wholeconstruction as far as possible.

These and other objects which will hereinafter appear are accomplished by this invention which is fully described in the following specification and shown in the accompanying drawings, in which:

Figure 1 is a broken vertical sectional view through the device; and y Fig. 2 is an enlarged section on the line 2 of Fig. l.

The embodiment illustrated comprises a central tube designated generally as A which carries at its lower end a lamp B and at its upper end a coupling C which is screwthreaded to receive the pipe D which extends through the ceiling E.

The central tube A need not be described in tion being transmitted to the lower section and consequently prevents much of this vibration being transmitted to the filament of the lamp itself. This flexible coupling also permits the lower section of the tube and the lamp itself to hang vertical even though the pipe D is somewhat out of vertical alignment.

The present invention relates to the method of mounting the canopy 11 which surrounds the central tube A. This mounting consists of a split sleeve 12 which loosely surrounds the upper tube section13, but which is preferably nfitted sufficiently tightly thereon to hold it against the weight of the sleeve itself by friction, This sleeve has a small flange 14 at the upper portion, the purposeof which will presently appear.

A ring 15 is fitted within the opening within the lower portion of the urn-like canopy 11, and hasatiangel which is rolled'tightly in placeso as toysecure it thereon. -The Vring 15 is slidable over the lower.l portion ofthe sieeve`12 and is prevented from passing over itby the flange 14. The ring 15 is provided with one or more screws 17 which areadapted to press in upon the sleeve 12 and to serve the double purpose of securing the canopy 11 on the sleeve 12 and also of compressing the sleeve 12 on the tube section 13 so as to lock it' ofil the sleeve 12 and, since the ring 15 isV larO'ei' than the coupling 10, it passes over it as shown in dotted lines so that the canopy 11is entirely out of the way of the operator.

The electric light leads 18 and 19 may now be brought vthrough the opening 20 in the.

ildes of the fitting C and spliced as shown at During this operation the canopy 11 is lowered to a oint where it is completely out of the way of the operator so that it does not interfere with him in any way. After the splices are made, the canopy 11 is raised and the ring 15 slid over the sleeve 12 and the whole slid up along the tube section 16 until the pop of the canopy rests against the ceillllQ; 1.1.

It will be understood that while this is described as a ceiling fixture, it can also be used as a wall fixture and that the enlargement lOmay be any enlargement on the tube and not necessarily a 'iexible coupling.

lVhile I have shown and described but a .single embodiment of this invention, it is to able on the tube, a rim on the inside of said sleeve to prevent the withdrawal of said canopy, an enlargement on the tube below the sleeve, and a canopy having ,an opening adapt-ed to fit over said sleeve and to pass over said enlargement.

l 2. In a ceiling 'fixture ia tube, a sleeve sli-dable on the tube, an enlargementfon the tube below the sleeve, a canopy having an opening adapted rto t over said sleeve and t0 pass over Said enlargement, and means lfor, sil-nul taneously securing said canopy on said sleeve and said sleeve on said tube.` y l 3. In a Ceiling fixture, a tube, a split sleeve slidable on the tube, yan exilim-,gement on the tube below the sleeve, a canopy having an opening actaptecl it'o t over said .sleeve and to .pass ov-ei' said enlargement, and a screw iin Said ACanopyadapted to bear upon said sleeve to secure both the'eanopyand the sleeve in adjusted position on' said tube.

In a ceilngxture, a tube, a split Sleeve slidable on thev tube, an enlargement on the tube lbe'low' the sleeve, `a canopy having `an opening adapted "to fit over said sleeve, a ning in said opening adapted to tit over said sleeve, and a Screw in said ring for securing sadfcanopy anat-sleeve on saidtube.
